Patent DE-2416837-A1 (DE)
Title: Process conditions analyzing in freeze drying plant - by means of samples in a reduced pressure chamber under reduced heat
Inventor: MIHALY ALEXANDER DR
IPC: F26B5/06
Filed: 1974-04-06
Abstract: A first sample is subjected to heat radiation and this heat is cut off during melting of the sample and the values retained. The next sample is then subjected to a lesser (1st) heat and an even more reduced (2nd.) heat and the heat is cut off during melting whilst the values for the amount of heat and durations are recorded. This process of progressively reduced heat application is continued with other samples until no melting takes place in a sample and the sample is finish freeze dried. Based on the valves thus obtained the process conditions for a large plant are given.

Title: Spin stabilised missile with proximity fuse - derives fusing criterion from amplitude modulation depth of receiver oscillations resulting from non-symmetrical directive pattern
Inventor: SCHMUCKER GEORG
IPC: F42C13/00
Filed: 1974-10-16
Abstract: The spin-stablised missile with a proximity fuse uses radar, infrared or laser transmitters. It is used against ground targets. The angle of impact can be individually set and the dispersion height correspondingly corrected. By a predetermined dependence of the explosion height w.r.t. the angle of impact in the target area, a directive pattern of the fuse sensor is selected which is non rotational symmetric w.r.t. the length axis of the missile. The fixing criterion is derived from the amplitude modulation depth of the fuse receiver oscillations resulting from the non-symmetrical directive pattern. The middle output signal amplitude in the receiving channel of the fuse is kept constant. The angle of impact is derived through measuring the rise in amplitude.

Title: Multicyclone with air bleed to dirty side - to ensure uniform and consistent loading of the cyclones
IPC: B04C5/28
Filed: 1975-02-28
Abstract: Multicyclone consists of several cyclone tubes arranged in essentially vertical arrangement having dip pipes extending from the top and having annular inlets around them opening into the dirty gas space and through which the dirty gas is drawn by means of a clean gas fan on the cyclone outlet. There is at least one other branch which connects the dirty gas side with the atmosphere, the cross-section of which is adjustable with respect to the pressure in the dirty gas side. In particular the dirty gas side is connected to the pressure side of the fan, with a butterfly valve in the line controlled by the pressure in the dirty gas space. The cyclone is used in separating dust from gas streams. The efficiency of such cyclones depends on maintaining an adequate gas flow. With reduced flow or different temps. the efficiency falls off. The mechanism allows this to be corrected and a constant high efficiency to be achieved.
